For those of you who must play Pokemon Go on the go but don’t want to waste the battery of your smartphone by having the app on all the time or don’t want to run the app unless there are actually Pokemons to catch, you may want to consider running the PokeDetector app, which runs in the background and only notifies you via vibration/sound/Android Wear watch when Pokemons are nearby.

This will also free you from watching the screen of your phone while walking around so you will be more safe while still being able to capture all the Pokemons you encounter. This app requires no root and only needs your Google login to use.
